- This invention relates to pliers for applying ear tags, though not necessarily restricted thereto. y f

The principal 'object of the invention 1s to make a single pair of pliers adaptable forapplying ear tags of different sizes or kinds, Vor forV performing a number of dierent operations. l

f he characteristic feature of the present in- Vention comprisesfa rotatable element mount ed'in one ofthe jaws'of the pliers, said rotatable 'element having a number of different faces which may successively bebrought 1n operative conjunction with the other jaw kfor performing predetermined operations.

The features of his'invention .for which the protectionof Letters Patent of the United States ris desired, are collectively grouped in the claims concluding this specification.

VIn theV drawings, which ill'ustratefseveral embodiments of this invention,

Fig. 1 represents avvertical center section taken through a lpairrof'pliers withfjan ear tag in place, ready to be operatedpupon; parts of the handles being broken away;

F ig.2, a front elevation, ear tag omitted; 'Fig-3,' a section on line 3-3, Fig. 1, parts in the background omitted; F ig. 4, a viewin perspectivey of the rotatable element, alone; 'Y Fig. 5, a viewv similar to Fig. 1, showing however, kind; n Fig. 6,' a view in perspective of the lower j awof the kind indicated in'Fig. 5; y; "Fig 7,' a section onv line 7-7,'Fig. 5, parts in the background omitted; Fig. 8, a vertical center section similar to Fig. l, but showing still another construction of the rotatable element and lower jaw; and

A Fig 9, a front elevation ofthe lower jaw indicated in Fig. 8.

Referring to the drawings, the numeral 20 Aindicates the lower jaw and the numeralV 21 the upper aw of a pair of compound ear tagy Vwall has been`removed,asclearly shown in the inner cylindricalsurface ofthe Vjaw poring mouth a rotatable element of a different Q tion 20-1 vof thejaw 20,.and"be fastened pliers having the handles V24 and 25.l Jaws 2O and2l Vmay be pivoted together at 26,'while the handles 24and 25 may be 'pivoted respectively, to the'jaws 20 and 21, at 28 and 29,.'thehandles in turn being pivoted together 50 at ,27 to forma fulcrum. f

Theforward-l portiony 20-1 of the lowerv jaw has preferably. the shape of an open cylinder'from which the upper portion of the Figs.V 2 and 3,thusleaving an open capsule` or 'cradle 'as' a holder for a barrel 3Ovrotat-` ably disposed therein.l The barrel *has 'the bearing portions 31, which fit snugly against tionj .QQ-1. Eachof the bearingportions 31 may have its rear portion notchedasinv dicated at 32, each notch having the taper# Between eachpair of bearing portions 31 is a depressed, substantially flat bed 34,35and 36. The bed portions 34, 35 and 36, respectively, may be provided with the. clinching wells -341,.35'-1, and 36. '1asl well as the stop portions134-2, 35-2 and 36'-2.-.The forward end of lthe barrel' may be closed'by a head 37,-which maybe soldered, welded, or otherwise fastenedin place.vv The barrel is preferablyr so arranged that the bearing portion 31 shall be l diametricallyopposite each oneof 'the beds 34,35 and Y36', thereby being` in position to resist the stress manifested' when the pliers are closed to-v gether in clinching an ear tag. rFliebarrel 30 vmaybe insertedpin-the portherein-in 'any position wherea bed shall` be at the top ofthe jaw, by bringing the notched portion 32 ofthe opposite bearing portion 31 Vinto registry with a bolt 38, which latter passes through a hole 39 in the bottom Vof the. portion 20-1 The bolt 38 may havea nut 38-1 anda knurledhead 38-2.

A disk 40 havingthe hub 40-1 is `rotatably mounted on the Vfulcrum pin 26, and has the notches 44, 45 and 46, whichV operatively correspond to the bed portions 34, and 36, respectively.

The disk may be rotated to bring any of the notches 44, and 46, into operative conjunction with the corresponding beds 34, 35 or 36, and be nominally held in each of the conjunctive positions by means of a spring 41 which is fastened at 41-1 to the web 21-1 of the aw 21. Spring 41 has a curved finger 41-2, which engages the notches 47, 48 or 49 of the disk, as the case may demand.

Thevpurpose of notched portions 44, 45 and 46, is to form back stops for holding tags in operative positions. Clearly, tags of diifer-V ent sizes require notchedgportions of different sizes.

A second form of this invention is shown in Figs. 5, 6 and 7. In this form, the lower jaw may have the side pieces 50, end piece 51, and the shelf or bracket 52, which latter extends forwardly from the end piece 51. The side pieces 50, end piece 51, and shelf 52, may all be integral with one another, being preferably stamped out of a single plate and afterwards bent into the-shape indicated. A die member 54, pivoted at 56 to the end piece 51, may be rotatable in the shelf 52 and be secured in the desired position by means of a thumb screw 57. The thumb screw may pass through a hole 58 in the bracket, and be secured in any one of the threaded holes 59 corresponding to the particular die, suoli as 54-1, which at that time may be in the operative position.

A third form of the invention is shown in Figs. 8 and 9. In this form, the lower jaw may consist of side pieces 62, integrally connected to the bottom piece 63. A pin 64 may extend transversely through the side pieces 62 and have rotatably mounted thereon, a die block 65. The die block has the die faces 65-1, 65-2, 65-3 and 65-4, and may be rioidly positioned in the lower jaw by means of a screw 67 extending through any one of ff the holes 68, vwhich corresponds to the particular die 65-1 to 65-4 that may be in use.

ln the forms shown in Figs. 5 and 8, the centering disks 60 and 70 are similar to the centering disk 40 in Fig. 1, and are nominally held in place by the springs 61 and 71, respectively.

It will be noted that in the forms shown. in Figs. 1 and 5, the axes of rotation of the die members are transverse to the pivotal axes of the jaws, while in the form shown in Fig. 8, the axis of the die member is substantially parallel to the pivotal axis.

rlhe closing and clinching of ear tags during the process of applying them to animals, is well known, and hence is not here described in detail.

Vhile desirable speciic embodiments of this invention are herein shown and described, it is to be clearly understood that all the detailed parts thereof, are not necessarily shown in the preferred forms, so that various changes can be made without departing from the spirit and scope of the invention as defined by the following claims in which its essential and characteristic parts are enumerated.
